    the video image of the eye and determines where
    the user is looking on the screen.
  • uses infrared light to illuminate the eye

44
Calibration on the Eye Gaze System
  • 15 Second Evaluation

45
How does the EyeGaze System work?
  • Eyegaze System uses the Pupil-Center/Corneal-Refle
    ction method to determine the eye's gaze
    direction.
  • Specialized image-processing software in the
    Eyegaze computer identifies and locates the
    centers of both the pupil and corneal reflection.
